Created as a tribute to London's Serpentine Gallery, the unisex fragrance by Comme des Garcons costs 56 pounds.

Its bottle and box was designed by British artist Tracey Emin.

It was designed to mark the opening of the Serpentine Gallery's new wing, reports a website. It has notes of grass, leaves, pollen, oxygen, asphalt, and 'a little bit of pollution,' according to Dover Street Market's website.

Comme des Garcons has used the distilled essences of juniper wood, gaiac wood and benzoin (a tree resin) to evoke London's city smell.

Similarly, the label has mixed a variety of black musks and nutmeg to create an asphalt-type scent.
